Research on transportation risk prediction method based on coupling analysis

With the continuous development of my country's economy, my country's road traffic is also constantly being constructed, and people's traffic travel has also shown a diversified development, which makes people put forward higher requirements for safe travel. For a long time, due to the lack of understanding of the disaster mechanism and causes of road traffic accidents in my country, the ability to prevent and control road traffic accidents in my country has been affected to a large extent. The quality of life and economic development of residents have been seriously affected. In order to reduce the probability of traffic accidents, it is very important to carry out effective risk assessment of road traffic accidents, evaluate the risk level of roads and formulate corresponding management countermeasures. Finally, taking a road as an example, the constructed road traffic risk assessment model is applied.
